Can someone help me ... I'm new on MAC OSX ... but I use to
work with FW !
On this OS, FW don't want to let me write with accent :
é, à, ï ... won't appear.
If I check with popchar the font table, i see that the accent
are in the unicode tab... so I suppose that FW have some trouble
with unicode font on mac.

I don't believe that you can type as you would with MS Word
or Illustrator and have the accented characters appear as you type.
However, you can create a text block and type with the keyboard
normally and when you require an accented character you can insert
one manually from the Special Characters panel as I mentioned in my
last reply.

One other option is to import your text from Photoshop CS2 or
Illustrator into Fireworks. See the Fireworks help menu for details
of how to do this. Text can be imported and remain editable or even
used as vector objects.

One final note; you could search for a Fieworks Extension
that may exist for creating the feature that you are after.
